Name the two kinds of fermentation

Question

Name the two kinds of fermentation? Also write down their chemical equations?

Answer 1

The two main kinds of fermentation are lactic fermentation and alcoholic fermentation.

In alcoholic fermentation pyruvic acid, an intermediate molecule is transformed into ethanol with release of carbon-dioxide. The alcoholic fermentation equation is shown below:

C₆H₁₂O₆ + 2 ADP + P --> 2 C₂H₅OH + 2 CO₂ + 2 ATP

In lactic fermentation pyruvic acid is converted into lactic acid and there is no production of carbon-dioxide. The lactic fermentation equation is shown below:

C₆H₁₂O₆ + 2 ADP + P --> 2 C₃H₅OOH + 2 ATP
